Sperilicniion formingpurt of Letters Patent No. 48,427, dated June .'27, lrlbr.

To all whom tft witty concern:

Beit known that I, U. A. NEUHAUS, ofthe y city, county, .und Stateof New York, have invented a new und useful linproveuientin Bungs l'or Barrels; and I do hereby decia-re that the following is a i'ull,clear, and exactdescription thereof, which will enable 'those skilled in the art to make and use the same, reference being Ahad tothe accompanying drawings, forming part of this specification, in whieh- V Figure l represents a verti al central. see tion of this invention, the line .r rv, Fig. 2,1m-

die'atinf,r the plane of section. Figi. 2 is' a plan' or, top View ofthe same.

'lzhis invention consists in a bung provided with a4 cone-valve, the seat of which is in a tube `screwed in tlie bung, in combinationwith a spring, which` has a tendency to keep the valve tight in its seat, and with. a lever, by

. nineans ot' which the valve can be opened in such a manner that whenever it isV desired to A represents a bung, made of wood or anyA hole, a., extendingin the direction of itslon `gitudinal center until it meets amortise, b,

ent in a direction transversely to the axis ot' the bung. The hole a-'is provided with a screwthread to receive a tubular plug, c,ot' metal or any other suitable material, andthe outer. end

` of this plug` toinis the seat i'or the cone-Valve d. i

This valve is secured to a stem, a, .which exi tends up through tlie tubular plug e, and is ,provided with a headf, at its upper end, as clearly shown in Fig.l of the drawings. A

spiral spring, g, interposed between the head f and the inner end of the tubular plug has' a tendency to keep the valve d in its'seat.`

B is Aa lever, which is fitted into the inortise rI), and which has its fulcrum on a pin, l1., passing transversely through the bung.,r A. The lever B is provided with a linuclile,1'., which rests Yon the head j' ol" the valve-stein. By depressing the outer end ot' the lever the valve is opened. l

This bung is intended partieularly for barrels containing ett'erveseent liquids, such as beer,

ale, 85e., and it is ofgreat advantage, because,

whenever it is desired to draw some ofthe eontents of the barrel, the requisite quantity otl atmospheric air necessary to cause the liquid to 'tlo'w oanbe admitted at any moment simply-by depressing the lever B, andas soon as saidlever is released :the barrel is hermeti cally closed and the carbonio acid or other gaseous constituents. of the liquid inthe bar-4 'relarc not permitted to escape. By this means the beer or other liquid retains its lifer until v,the last drop is drawn from the barrel.

Having thus described my invention, Iclaiin as new and desiretosecure by Letters Patentother-suitable material, and provided with' a` 'A bung provided with a tubular pluggc,

spring-valve d, and lever B, substantially as Witnesses:
